The IRG has contributed several blocks of characters to Unicode / UCS, including the CJK Unified Ideographs, CJK Compatibility Ideographs ( and Supplement ), and CJK Unified Ideographs Extensions A, B, C, and D. CJK Unified Ideographs Extension E is in preparation, as of Unicode 6. 0.

It is similar to Unicode but does not use Unicode's Han unification process: each character from each CJK character set is encoded separately, including archaic and historical equivalents of modern characters.

Unicode discourages their use for mathematics and in Western texts because they are canonically equivalent to the CJK code points U + 300x and thus likely to render as double-width symbols.

For the purposes of compatibility with Chinese, Japanese and Korean ( CJK ) characters, Unicode has symbols for:

The CJK character sets take up the bulk of the assigned Unicode code space.

Han unification is an effort by the authors of Unicode and the Universal Character Set to map multiple character sets of the so-called CJK languages into a single set of unified characters.

One possible rationale is the desire to limit the size of the full Unicode character set, where CJK characters as represented by discrete ideograms may approach or exceed 100, 000 ( while those required for ordinary literacy in any language are probably under 3, 000 ).

Version 1 of Unicode was designed to fit into 16 bits and only 20, 940 characters ( 32 %) out of the possible 65, 536 were reserved for these CJK Unified Ideographs.

Later Unicode has been extended to 21 bits allowing many more CJK characters ( 75, 960 are assigned, with room for more ).

Unlike European versions, CJK Unicode fonts, due to Han unification, have large but irregular patterns of overlap, requiring language-specific fonts.

Glyphs for CJK ideographs are reworked to look more like Arial Unicode MS, while sub-glyphs for these characters are repositioned and rescaled.

More code points are now associated to characters due to update of Unicode, especially the appearance of CJK Unified Ideographs Extension B.

The SimSun 18030 font includes all the characters in Unicode 2. 1 plus new characters found in the Unicode CJK Unified Ideographs Extension A section, but despite its name, it does not contain glyphs for all GB 18030 characters.

Note that all ( about a million ) Unicode code points up to U + 10FFFF can be encoded as GB 18030, hence “ a font that fully supports GB 18030 ” would mean a font that contains glyphs for all Unicode characters, not only for CJK ones.

The Unicode standard also has attempted to create a unified CJK character set that can represent Chinese ( Hanzi ) as well as the Japanese ( Kanji ) and Korean ( Hanja ) derivatives of this script through the Han unification process, which does not discriminate by language nor region for rendering Chinese characters, as long as the different typographic traditions have not resulted in major differences concerning what the character looks like – see: Image: Xin-jiu-zixing. png for examples of characters whose appearance recently underwent only minor changes in Mainland China.

The mandatory part of GB 18030-2005 consists of 1 byte and 2 byte encoding, together with 4 byte encoding for CJK Unified Ideographs Extension A.

The need to support more writing systems for different languages, including the CJK family of East Asian scripts, required support for a far larger number of characters and demanded a systematic approach to character encoding rather than the previous ad hoc approaches.

In CJK environments where there are several different multi-byte encodings in use, auto-detection is also often employed.

This is a compatibility character encoded for roundtrip compatibility with legacy CJK encodings ( which included it to conform to layout in square ideographic character cells ) and vertical layout.

However, the standard makes no provision for the scripts of East Asian languages ( CJK ), as their ideographic writing systems require many thousands of code points.

Fonts covering the CJK characters usually include not only the script small but also four precomposed characters: < span style =" font-size: 112 %">㎕, ㎖, ㎗</ span >, and < span style =" font-size: 112 %">㎘</ span > ( U + 3395 to U + 3398 ) for the microlitre, millilitre, decilitre, and kilolitre.

The CID-keyed font format was also designed, to solve the problems in the OCF / Type 0 fonts, for addressing the complex Asian-language ( CJK ) encoding and very large character set issues.

In Chinese, Japanese, and Korean ( CJK ) fonts, these characters are rendered at the same width as CJK ideographs, rather than at half the width.

The increased pin-count permitted superior print-quality which was necessary for success in Asian markets to print legible CJK characters.

East Asian rules of typography, for example, require CJK fonts to always be monospaced at least as far as the main characters for writing words ( i. e. not punctuation ) are concerned.

OpenOffice. org version also supported Windows ME / 2000 for Asian / CJK versions, generic Linux 2. 2. 13 with glibc2 2. 1. 3, Solaris 7 SPARC ( 8 for Asian version ).

They are useful for East Asian fixed-width CJK typography, because they are equal in proportion to one Chinese character.

Traditionally, all CJK languages have no spaces: modern Chinese and Japanese ( except when written with little or no kanji ) still do not, but modern Korean uses spaces.

CJK is a collective term for Chinese, Japanese, and Korean, which is used in the field of software and communications internationalization.

The term CJKV means CJK plus Vietnamese, which constitute the main East Asian languages.

Although CJK encodings have common character sets, the encodings often used to represent them have been developed separately by different East Asian governments and software companies, and are mutually incompatible.

The name " COMPAQ " was said to be derived from " Compatibility and Quality " but this explanation was an afterthought.

AT & Ts Compatibility Bulletin No. 105 described the product as " a method for pushbutton signaling from customer stations using the voice transmission path.

A complete ABI, such as the Intel Binary Compatibility Standard ( iBCS ), allows a program from one operating system supporting that ABI to run without modifications on any other such system, provided that necessary shared libraries are present, and similar prerequisites are fulfilled.
